Coupling of HRT II and AS-OCT to evaluate corneal endothelial cell loss and in vivo visualization of the Ahmed glaucoma valve implant

Abstract

Aims To report corneal endothelial cell loss and in vivo visualization of the Ahmed glaucoma valve implant in eyes with refractory glaucoma. Methods Ten eyes underwent Ahmed valve implant surgery and were followed-up for 12 months. Data collected included intraocular pressure (IOP

Value of optical coherence tomography for anterior segment surgery

“…Guthoff et al 80 show that encapsulated blebs can be easily identified using AS-OCT, which provides information about the height of the bleb and the internal morphology, which can be used to identify blebs that are suitable for bleb needling. Furthermore, AS-OCT can be used to assess the patency and position of tubes after glaucoma drainage implant surgery ( Figure 14) 81 and is especially useful in patients with an opaque cornea or vulnerable cornea; for example, shortly after PKP. 82 Anterior segment OCT can also evaluate the effectiveness of iridotomies.…”

Corneal endothelial cell loss after Baerveldt glaucoma drainage device implantation in the anterior chamber

“…2008; Mendrinos et al. 2009; Hau & Barton 2009). Endothelial cell loss was reported after Molteno glaucoma drainage device (GDD) insertion (McDermott et al.…”

Corneal Endothelial Morphology in Eyes Implanted With Anterior Chamber Aqueous Shunts

“…Conventional ultrasonography, 6 ultrasound biomicroscopy, 7 and more recently, anterior segment optical coherence tomography (AS-OCT) have been used to locate tube position and patency within the eye. 8,9 The purpose of this cross-sectional study was to explore the relationship between corneal endothelial cell density with potential influences such as number of previous operations, type of glaucoma, and shunt position in the AC.…”
